Terraform Push Configuration

Prior to v0.12, Terraform included mechanisms to interact with a legacy version of Terraform Enterprise, formerly known as "Atlas".

These features relied on a special configuration block named atlas:

atlas {
  name = "acme-corp/production"
}

These features are no longer available on Terraform Enterprise and so the corresponding configuration elements and commands have been removed in Terraform v0.12.

To migrate to the current version of Terraform Enterprise, refer to the upgrade guide. After upgrading, any atlas blocks in your configuration can be safely removed.
